文摘
- •
A novel sandwich-type electrochemical immunosensor was designed for detecting CEA.
- •
Ag@Cu2O nanocomposites were synthesized by a simple method and employed as labels.
- •
Ag@Cu2O nanocomposites have a high electrocatalytic activity towards H2O2.
- •
The immunosensor exhibited high sensitivity and low detection limit of 0.18 fg/mL.
